Matplotlib: How to remove dark horizontal/vertical dots at the end of grid lines in?

Question

How to remove dark horizontal/vertical dots, at the end of grid lines?

Here is my Code:

ax3.set_axisbelow(True)
plt.grid(b=True, color=self.x_grid_line_color, linestyle='-')

Answer 1

I suspect you're probably referring to the axis tick marks, which are normally also visible when there are no grid lines. You can turn them off using ax.tick_params() :

ax3.tick_params(top='off', bottom='off', left='off', right='off')

Answer 2

如果我理解正确，一种方法是使用plt.tick_params(length=0) 。
